"It is Shounen Jump's release date and information on the Bleach novel is contained in it, but let me supplement it.
The story of the '8th generation Kenpachi', and the 'story in connection to Mayuri' are contents which are in my novel, as for Matsubara san's (although I cannot reveal the details of which from my own mouth) it seems to be a story with a different content. I am also excited about Matsubara san's writing for the 17 unknown months!
Incidentally, I have revealed some various keywords but it is not a collection of short stories, but rather about one big incident. The stage I was able to write, adding the few paged scenes include: All of Karakura chou, Seireitei, 8th underground prison (eternal -Aizen prison-), Rukongai, HM desert, Las Nochces, Dangai (Senkaimon and Garganta).
And of course, the main character is Don Kanonji! For the other appearing characters aside from 8th Gen Kenpachi and Mayuri, I will be happy if you wait for further report. When I asked the person-in-charge, he/she said that what I can reveal is only up to this point. 'Isn't it weird that the 8th Gen is alive?' For the answer to these kinds of questions, please read the book!
Also, it was put as an announcement in Jump but what I wrote is also part of the '17 months, from when Kurosaki Ichigo lost his powers to before he meets Ginjou'. I will be happy if you will imagine this to be what happened between volume 48 and volume 49."
